摘要： An anti-skid device for vehicles comprising a wheel speed detector for producing an output signal upon detecting that the wheel speed is below a predetermined value, a first timer circuit for producing an output signal when the output signal from the wheel speed detector remains on for more than a definite time, and a second timer circuit for energizing the braking force modulator only for a definite time upon receipt of the output signal from the first timer circuit, whereby the locking of wheels due to a braking operation by the driver may be prevented.

摘要： AN ANTI-SKID DEVICE FOR AN AUTOMOTIVE VEHICLE IS DISCLOSED COMPRISING A WHEEL SPEED VOLTAGE GENERATOR FOR GENERATING A WHEEL SPEED VOLTAGE CORRESPONDING TO A WHEEL SPEED, A REFERENCE WHEEL SPEED VOLTAGE GENERATOR WHICH GENERATES A REFERENCE WHEEL SPEED VOLTAGE CORRESPONDING TO A REFERENCE WHEEL SPEED WHICH, BEING INITIALLY LOWER THAN A WHEEL SPEED, IS REDUCED AT A FIRST SET DECELERATING RATE WITH THE DECREASE IN WHEEL SPEED AT THE TIME OF BRAKING. A DIFFERENTIAL AMPLIFIER WHICH GENERATES A SIGNAL TO REDUCE THE BRAKING PRESSURE WHEN SAID REFERENCE WHEEL SPEED VOLTAGE IS HIGHER THAN SAID WHEEL SPEED VOLTAGE, SAID WHEEL SPEED VOLTAGE GENERATOR, REFERENCE WHEEL SPEED VOLTAGE GENERATOR AND DIFFERENTIAL AMPLIFIER CONSTITUTING A LOCK DETECTOR MEANS. A PRESSURE DIFFERENCE DETECTOR IS PROVIDED FOR GENERATING A SIGNAL WHEN THE BRAKING PRESSURE OF A WHEEL CYLINDER IS EQUAL TO THAT OF A MASTER CYLINDER, WHILE A CONTROL MEANS SWITCHES SAID REFERENCE WHEEL SPEED VOLTAGE GENERATOR FROM A FIRST SET DECELERATING RATE TO A LOWER SECOND SET DECELERATING RATE WHEN SAID PRESSURE DIFFERENCE DETECTOR GENERATES A SIGNAL AFTER THE GENERATION OF A BRAKING-PRESSURE REDUCING SIGNAL BY SAID DIFFERENTIAL AMPLIFIER, AND A BRAKING PRESSURE MODULATOR MEANS REDUCES THE BRAKING PRESSURE ACCORDING TO A SIGNAL FROM SAID DIFFERENTIAL AMPLIFIER. THE MAXIMUM VALUE OF THE FRICTION COEFFICIENT BETWEEN THE WHEELS AND A ROAD SURFACE IS SOUGHT WHILE THE MAXIMUM TIRE TORQUE CORESPONDING TO SAID MAXIMUM FRICTION COEFFICIENT IS OBTAINED, TO CONTROL THE BRAKING PRESSURE EFFICIENTLY AND SAFELY ON A ROAD SURFACE WITH ANY FRICTION COEFFICIENT FROM A FROZED ROAD TO A CONCRETE-PAVED ROAD WITHOUT THE LOCKING OF WHEELS, IRRESPECTIVE OF THE MANNER IN WHICH A VEHICLE DRIVER APPLIED THE BRAKING FORCE TO THE WHEELS.

摘要： AN ANTI-SKID SYSTEM FOR VEHICLES IS DISCLOSED HAVING A NOVEL WHEEL LOCK DETECTING APPARATUS FOR SUPPLYING BRAKE RELEASE SIGNALS. THE EXEMPLARY SYSTEM INCLUDES AN ACTUAL WHEEL SPEED VOLTAGE GENERATOR FOR GENERATING AN ACTUAL WHEEL SPEED VOLTAGE CORRESPONDING TO AN ACTUAL WHEEL SPEED AS WELL AS A REFERENCE WHEEL SPEED VOLTAGE GENERATOR FOR GENERATING A REFERENCE WHEEL SPEED VOLTAGE CORRESPONDING TO A REFERENCE WHEEL SPEED. THE REFERENCE WHEEL SPEED VOLTAGE EXISTS ACROSS A CAPACITOR AND DECREASES WITH A FIRST DISCHARGING TIME CONSTANT VALUE CORRESPONDING TO A FIRST PRESET DECELERATION VALUE. THE REFERENCE VOLTAGE STARTS DISCHARGING FROM AN INITIAL VALUE WHICH IS LOWER THAN THE ACTUAL WHEEL SPEED VOLTAGE WHEN THE RATE OF REDUCTION OF ACTUAL WHEEL SPEED VOLTAGE REACHES A VALUE CORRESPONDING TO SAID FIRST PRESET DECELERATION VALUE. A DIFFERENTIAL AMPLIFIER IS INCLUDED FOR PRODUCING AN OUTPUT SIGNAL TO REDUCE BRAKING PRESSURE WHEN SAID REFERENCE WHEEL SPEED VOLTAGE BECOMES HIGHER THAN AN ACTUAL WHEEL SPEED VOLTAGE. THERE IS ALSO A DETECTOR FOR DETECTING A PREDETERMINED VARIATION IN THE ACTUAL WHEEL SPEED VOLTAGE DURING A TIME STARTING FROM THE TERMINATION OF THE OUTPUT SIGNAL FROM SAID DIFFERENTIAL AMPLIFIER OR, IN OTHER WORDS, AFTER THE BRAKE RELEASE SIGNAL TERMINATES. A TIME CONSTANT SETTING DEVICE IS PROVIDED FOR SWITCHING THE DISCHARGING TIME CONSTANT CORRESPONDING TO SAID FIRST PRESET DECELERATION VALUE TO A SECOND DISCHARGING TIME CONSTANT VALUE CORRESPONDING TO A SECOND PRESET DECELERATION VALUE, WHICH IS SMALLER THAN THE FIRST. THE SWITCHING BETWEEN FIRST AND SECOND DISCHARGE TIME CONSTANTS IS CONTROLLED BY AN OUTPUT SIGNAL OF SAID DETECTOR TO THEREBY CONTROL THE REFERENCE WHEEL SPEED VOLTAGE GENERATOR, WHEREBY THE WHEEL LOCK DETECTING APPARATUS ACCURATELY DETECTS ANY TENDENCY OF THE WHEELS TO LOCK AND PRODUCES A BRAKING PRESSURE REDUCING SIGNAL TO ACTUATE A BRAKING PRESSURE MODULATOR THEREBY REDUCING BRAKING PRESSURE.

摘要： An antiskid control device for vehicles, comprising a timer circuit for producing a timing signal in synchronism with the extinction of a release signal for a skid control, apparatus for rapidly increasing the braking pressure applied to the wheel in response to said timing signal coming from the timer circuit, and correcting apparatus for increasing the braking pressure increasing rate when a large amount of friction is present between the wheel and the road surface, said antiskid control device being able to hold the fluctuation of the braking pressure within a narrow range to prevent unnecessary vibrations of the vehicle at the time of braking due to the fact that the braking pressure increasing rate is changed when the braking pressure is reapplied to the wheel, and being able to control the braking operation at all times in a manner best suited to the various road surface conditions encountered so that a skid of the vehicle is prevented from occurring and the braking distance is reduced greatly, due to the fact that the braking pressure increasing rate is adjusted in accordance with the coefficients of friction between the wheel and the road surface.

摘要： A radiator cap composed of a cap body, a compression gasket assembly connected to the cap body and adapted to open and close in accordance with the pressure of the coolant in the radiator, a float engaged with the cap body so as to move up and down in accordance with the level of the coolant. The upper edge of the float is formed so that upon contact with a gasket assembly, a valve is formed with said gasket assembly. A reed switch secured to the cap body is opened or closed in response to movement of the float so that the reed switch actuates suitable warning means when the level of coolant falls over a predetermined line.

摘要： Discriminator circuits connected to the sensors produce an output signal when the associated sensor generates a signal indicating an abnormal state of the part or area monitored. Reproduction units display the abnormality by means of the discriminator output signal. An OR gate circuit has its input terminals connected to the output terminals of the discriminator circuits in a number of reproducing circuits for abnormal states. A main alarm units indicates abnormality in response to the OR gate circuit output signal. A checking unit verifies the operating state of the reproducing circuits and a circuit containing the main alarm unit.

摘要： An improved liquid level detecting and indicating system for vehicles comprising a pair of liquid level detecting elements which are arranged in opposite positions on the detecting level of a liquid in a liquid container installed in a vehicle, whereby when each of the liquid level detecting elements sends a signal indicating that the liquid level has dropped below a reference liquid level, an indicator is brought into operation. In this way, the level of liquid can be accurately detected and indicated without being influenced by the inclination or vibration of a vehicle body.
